Watch: Trailer for 'The Babadook,' One of 2014's Best Horrors

In this nerve-ratcheting haunted house tale by way of Roman Polanski’s "Repulsion," Essie Davis gives a breakthrough performance as a woman struggling to cope with– and even love — her disturbed six-year-old son.

What begins as a gloomy mother-son drama with etchings of "We Need to Talk About Kevin" goes horrifically bat-shit after he opens a creepy children’s book portending doom and bloodshed for both of them. And that’s all I’ll say.

Watch the official US trailer below. This 2014 Sundance knockout most recently picked up a bevy of prizes at Fantastic Fest.
